UNITED STATES PATENT OFFICE.

IRIVIN R. B. ARNOLD, OF WHEATON, ILLINOIS.

APPARATUS FOR GENERATING AND STORING OXYGEN.

SPECIFICATION forming part of Letters Patent No. 393,737, dated December 4, 1888.

Application filed December 19, 1887. Serial No. 258,367. (No model.)

To aZZ whom it may concern:

Be it known that I, IRWIN R. B. ARNOLD, a citizen of the United States, residing at lVheaton, in the county of Du Page and State of Illinois, have invented a new and useful Improvement in Apparatus for Generating and Storing Oxygen, of which the following is a specification.

My invention relates to an improvement in apparatus for generating and storing oxygen; and it consists in the peculiar construction and combination of devices that will be more fully set forth hereinafter, and particularly pointed out in the claim.

In the accompanying drawings, Figure l is a perspective view of the apparatus embodying my improvement. Fig. 2 is avertical sectional view of the same, taken on the line :0 a; of Fig. 1. Fig, 3 is a detail view of an attachment.

A represents a cylindrical receiver or reservoir, from the upper end of which extends a vertical pipe, B.

0 represents a pipe, which has its central portion connected to the upper end of pipe B, said pipe 0 being arranged horizontally and having its extremities projecting in opposite directions, one arm of the pipe 0 provided with a globe-valve or stop-cock, D, and the other arm thereof is provided with a globevalve or stop-cock, E. The pipe Bis provided with a globe-valve or stop-cock, F.

G represents a pressure-gagemrhich is adapted to be connected to one end of pipe C by means of a screw-joint, as shown.

H represents a wash-bottle, of suitable c011- struction, which is adapted to be connected to the opposite end of pipe C by means of a screw-joint, I.

K represents the retort, from one end of which extends a pipe, L.

M represents a connecting-pipe, which is adapted to be connected to one end of the pipe L by a joint, M, andto the goose-neck P at the upper end of the wash-bottle by means of a screw-joint, O.

R represents a T-coupling, which is adapted to be attached to one end of the pipe 0 when the wash-bottle is disconnected therefrom, the said T- coupling being adapted for the attachment of a pipe to lead to a calcium light, and the said T-coupling is provided with a needle-valve, S, by means of which the quantity of gas discharged from the receiver or reservoir can be regulated.

The object of my invention is to provide an apparatus by means of which oxygen may be conveyed from the retort, under pressure, to the receiver and stored in the latter without the necessity of employing a pump or other means for forcing the oxygen from the retort into the receiver, and thereby effecting an economy in the structure of the apparatus and enabling the same to be placed on the market at a small cost.

The operation of my invention is as follows: The stop-cocks D,E, and F are normally closed, the wash-bottle is normally disconnected from the pipe 0, and the retort is normally disconnected from the wash-bottle. The retort is first heated over a moderate fire until it is hot and dry, whenit may be laid across a pail of cold water and water poured over it until the upper portion of the retort is cold. Care is then taken to see that the packing in the screwjoints is ready for coupling the parts of the apparatus together, the wash-bottle is loosely jointed to the arm 0, the connecting pipe M is firmly joined to the goose-neck of the wash-bottle, and a charge of mixed chlorate of potash and black oxide of manganese is placed in the retort, and the pipe L is then firmly jointed to the pipe M. Oxygen is immediately generated in the retort and expels the air therefrom through the loose joint which connects the wash-bottle to the pipe O,'

and the said joint is then tightly secured and the stop-cocks or globe-valves D, E, and F opened, thereby permitting the oxygen to be discharged directly into the receiver and stored therein at a sufficiently high pressure. By noting the pressure-gagethe pressure of the oxygen in the receiver maybe ascertained at any time, and when it is observed that the pressure is at its maximum and the oxygen is all accumulated in the receiver the globevalves or stop-cocks are closed, so as to prevent the escape of the oxygen from the receiver, and the wash-bottle and the retort are then disconnected. In order to convey the oxygen to a calcium light or other point where it is to be used, the T-coupling R is screwed to one end of the pipe 0, and a suitable conveying-pipe is also attached to the said T-coupling. The

e-lohe-vnlves or stop-eoeks are then opened, which permits the oxygen to How through the Feoupling to the light or other point where it is eonstnned, and by means of the needle- \zllVO H the How of the oxygen from the reeeiver may be regulated at will.

Having thus deserihed my invention, 1 claim-- In uppztrntustor generating and storing oxygen, the eomhinntion of the receiver A, havin the pipe B. provided with a valve, F, and 1 2|. pipe, t, connected to pipe B and provided with the valves 1) and E, the pressure-gage adapted to he connected to pipe C or disconnected therefrom, the wash-bottle adapted to p IRWIN R.
